Abstract
The subject of the future of the interactive Television medium has become a topic of great interest to the academic and industrial communities particularly since in the recent years there has been a dramatic increase in the pace of innovation of convergence of digital TV systems and services. The purpose of this paper is to provide a brief overview of what we know as digital TV converged services, to present and categorise the digital Television middleware technologies that contributed to it, and to present possible future trends and directions. A new Television era of converged wireless and mobile content delivery, user-authored content, multimodal interaction, intelligent personalisation, smart space awareness, and 3D content sensations is foreseen, creating ambient and immersive experiences.

Interactive Television has been the subject of dramatic innovation in the recent years transforming a traditionally passive medium into a truly interactive experience.Firstly there has been a trend towards more interaction giving the viewer control over video, audio, graphical, and text elements, by enabling him to consume simple games and quizzes and send simple communications back to the broadcaster
There has been a trend towards providing TV programmes over a much wider range of TV screen sizes ranging from High Definition (HD) to Standard Definition (SD) to Mobile Definition (MD) TV with a trend for certain programmes to be targeted to particular screen sizes
Summary
Interactive Television (iTV) has been the subject of dramatic innovation in the recent years transforming a traditionally passive medium into a truly interactive experience. Personalised TV includes the personal video recording function, which allows the viewer to pause live programming, fast-forward through commercials and record hours of programming without the use of videotape. This in turn is enabling viewers to skip over any 30-second advertising slot. This paper categorises and describes the various software solutions that render the interactive part of digital Television possible in different converged platforms. It presents and discusses future and emerging trends from technological, business and viewer perspectives that will shape the pace of innovation in the iTV domain
